Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle through passages, more particularly to a bottom support assembly of a rail vehicle through passage. BACKGROUND

[0002] A rail vehicle through passage refers to a passage connecting two carriages of a train, which allows passengers to move freely during train operation. The bottom support assembly is an important component of the through passage, which is responsible for supporting the weight of the through passage and ensuring its stability and safety during train operation.

[0003] In related technologies, in order to achieve the effect of facilitating observation of the wear condition between the treadle and the crossing plate for maintenance, for example, the prior art with publication number CN213799648U provides a through passage of a rail vehicle. The device forms a tread surface for passing through by the upper surface of the crossing plate and the upper surface of the treadle. The tread surface is constructed by the treadle and the crossing plate, facilitating passing through. At the same time, the treadle and the crossing plate are in sliding contact, ensuring that the crossing plate can digest the force through sliding contact under a bumpy vehicle condition, preventing the structure of the through passage from being damaged after multiple impacts, and improving the riding experience. In addition, the treadle and the crossing plate are in sliding contact through the energy consumption strip, which has good cushioning performance. The energy consumption strip is provided with an observation line along its length direction, facilitating observation of the wear condition of the energy consumption strip. The wear condition of the energy consumption strip is observed through the observation line, facilitating maintenance.

[0004] Although the above-mentioned prior art can achieve the effect of sliding contact between the treadle and the crossing plate through the energy consumption strip between the treadle and the crossing plate and facilitate observation of the wear condition of the energy consumption strip for maintenance, the treadle and the crossing plate are both installed in the through passage through hinge rotation and in sliding contact with each other as the bottom support structure of the through passage. Due to the lack of a connecting structure between the treadle and the crossing plate, the crossing plate and the treadle are easily lifted and opened. In particular, for children with curiosity, the easily opened treadle and crossing plate have poor safety performance.

[0005] In view of this, we propose a bottom support assembly of a rail vehicle through passage. CONTENT OF THE UTILITY MODEL
